    My client has the requirement to have a cold standby server for snmp_collector hub. When needed, they will swing from the "primary" snmp_collector hub server to the DR snmp_collector hub server. What do I need to do to accomplish this? My understand is the config data are in local DB, can I copy this DB (on top of metric family, cert, conf files) periodically to the standby snmp_collector server?

    Hi, I hope this KB give you some pointers to achieve your needs.

    https://comm.support.ca.com/kb/how-to-move-snmpcollector-probe-from-one-hub-to-another-hub/kb000103510

     

    One thing I would like to highlight - The same origin value shall be shared in between "primary" and "standby"

     

    Regards, Yu

    The instruction says that I need to:

     

    1. Open Template Editor in current snmpcollector probe and deactivate all active templates.

    2. Deactivate snmpcollector probe.

     

    The ideal plan is to able to backup the following files nightly:

    <snmpcollector>/snmpcollector.cfg
    <snmpcollector>/snmpcollector.mv.db
    <snmpcollector>/bulk_config/templates/*
    <snmpcollector>/CustomVendorCertifications/* (If you have self certification)

     

    The need to shutdown snmpcollector is not ideal. Questions are:

    1 - is that a way I can programmatically disable templates from command line

    2 - is deactiving snmpcollector probe a must? I am assuming the reason for this is to ensure we get a clean DB file copy. if I:

       a. copy the DB file while snmpcollector probe is running, how good is the DB file?

       b. instead of backing up the live DB files, can I copy the DB backup files and then restore them onto the "standby" snmpcollector hub?
